The Tolkien reference - to the film rather than the book - was the uprooting of the tree, and the destruction of The Shire.

I rather hoped that when it came to the deindustrialisation of Britain we'd have had Fred Dibnah blowing up the chimneys...

But I imagine there was lots of stuff going on that the TV didn't pick up - for example in a press photo I saw a large Yellow Submarine which never showed up on screen.
